Octal buffer/line driver; 3-state
The 74HC541-Q100; 74HCT541-Q100 is an octal non-inverting buffer/line driver with 3-state outputs. The device features two output-enables (OE1 and OE2). A HIGH on OEn causes the outputs to assume a high-impedance OFF-state. Inputs include clamp diodes that enable the use of current limiting resistors to interface inputs to voltages in excess of VCC.
This product has been qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 1) and is suitable for use in automotive applications.
